Why Bad Request image (#400) in yii2?

Question

Yii

I am editing a post, when I click Save, I get an error Bad Request (# 400)
I found out that the error is due to the output of the picture, if this code is removed from the form view

<?php 
   $img = $image->getPostImg($model->id);

           if(!empty($img->name)){
                
                 echo Html::img('https://site.ku/frontend/web/' . $img->name, $options = ['id' => 'blah', 'style' => ['width' => '180px']]);
            } 

?>

then the error disappears and everything is saved, the field itself remains and works fine

<?= $form->field($image, 'image')->fileInput(['id' => 'images-image', 'name' => 'Images[image]']) ?>

And when I go to edit the post and look at the source code, there is a picture there, but it is not displayed, and when you click on the link of this picture, they give the same error, but the picture is there

<img id="blah" src="https://site.ku/frontend/web/uploads/post/post_5bd33b14ab799.png" alt="" style="width: 180px;">

I do it in the admin panel in the backend from the admin with registered access and save the pictures in the frontend

'access' => [
                'class' => AccessControl::className(),
                'rules' => [
                    [
                        'allow' => true,
                        'roles' => ['AdminPanel'],
                    ],
                ],
            ],

I take it this is a permissions error? what's wrong?

Answer 1

Check if the form has a CSRF token. Most often, this error is precisely because of him. Especially if the logs say "failed to check the data."
